Petite Sizes

If you are 5'4" or under, our Petite sizes are designed just for you. Based on height rather than weight, our Petite sizes are proportionately shorter, not smaller. To ensure the best fit for you, we adjust the armholes, sleeve length, and total length of tops, as well as shorten the rise and inseam of pants and the lengths of skirts.

Women's Sizes

If you have a fuller figure, our Women's (plus) sizes are specifically designed to fit your body and flatter your shape. We make our Women's sizes proportionally larger by adding length to tops and dresses and increasing the circumference of the chest and waist so you can wear your favorite outfits with comfort and confidence.

All measurements are in inches.

How to Measure

Bust

Determining the right bra size

With your arms down and relaxed at your sides, 1-measure around the fullest part of your bust while keeping the measuring tape level and parallel to the floor (this is your bust size). 2-Then measure around the chest, above the bust under your arms (this is your band size). Subtract your band size from your chest size to get your cup size. Each inch represents a cup size; see below. (Helpful tip: Make sure the measuring tape is wrapped around your shoulder blades and under your arms.)

Waist

Breathe easy

3-While keeping the measuring tape comfortably around your waist and parallel to the floor, measure around your natural waistline. (Helpful tip: You can find your natural waistline by bending to one side and finding the indentation or crease.)

Hips

Keep the tape loose

4-Stand with your feet together and measure around the fullest part of your hips while keeping the measuring tape parallel to the floor. (Helpful tip: Your hips are about 7.5" to 8" below your waist.)

Inseam

Your best length

5-Holding the measuring tape perpendicular to the floor, measure down the inside of your leg from the crotch area to the base of your ankle. (Helpful tip: You can also find your inseam by measuring a pair of your favorite pants: Lay the pants on a flat surface and measure the inside leg seam from the crotch to the hem.)

Skirt Length

Make sure it fits just right

6-With the measuring tape perpendicular to the floor, measure from your natural waist along the outside of your leg to below your knee, mid calf, lower calf, or ankle. (Helpful tip: To find your natural waist, bend to the side and find the crease.)

Helpful Hints

  • Order oversized loungewear, dresses, sweaters, and tops nearest to your bust measurement.
  • Order pants, shorts, and skirts nearest to your hip measurement.
